The energy business has a way of making smart people look dumb. Experts were blindsided by the shale revolution in the United States. For most of the last few decades, they had assumed that U.S. domestic energy supplies were dwindling. Then, advances in horizontal drilling and hydraulic fracturing, or “fracking” -- the injection of high-pressure streams of sand, water, and chemicals into underground shale and other rock to unlock oil and natural gas trapped there -- significantly boosted total U.S. natural gas production, by as much as 25 percent in recent years, forcing many experts to change their tune.
